If you are building or remodeling and your kitchen and will have an island, here are 6 tips: Use for Seating. The best use of a kitchen island is seating. Kitchens are the center of a home and where the family collects. Additional seating for meetings and meals is always appreciated. Add Appliances. Placing a microwave, warning drawer, beverage fridge or wine cooler on an island due to the extra space it offers may be the difference of whether those components can be fit properly in the kitchen space. Put the Sink In. It frees up valuable counter space along the walls and works especially well where the kitchen has no window. If the main sink wont be in the island, a prep sink could go there instead.
